Common Issues
- Hook script permission errors: Ensure that the hook script has executable permissions.
- Non-existent hook names: Verify that the specified hook name is correct and supported by the repository.
- Syntax errors in hook scripts: Hook scripts must be valid shell scripts. Check for typos or errors.
